ZOOLOGY UNIVERSITY O F MICHIGAN NOTES ON A COLLECTION OF AMPHIBIANS AND REPTILES FROM THE STATE OF'

lections were made in various regions of the state in an attempt to obtain specimens from the different habitats. The localities where collections were made are shown on Map 1. These localities are found in two general areas. The first of these is the coastal region, which is characterized by dense vegetation and much humidity. There are numerous swamps and lagoons surrounded by thick hardwood forests, open scat-tered patches of savanna grassland, and a few arid portions with cacti and other xerophytic plants. I n this area are located Paso del Rio, Tecomhn, Pascuales, Manzanillo, and Santiago. The second general region is that of the plateau section, which is higher and drier than the coastal region. This area is composed of arid hills and elevated plains dissected by deep barrancas and covered with scattered patches of short grass and xerophytic shrubbery. I n the more humid portions there are occasional hardwood forests, and the barrancas are often filled with heavy growths of vegetation more characteristic of the coastal region. I n this area are situated Queseria, Comala
